ENVELOPE.

SPECIFICATION forming part of Letters Patent No. 521,431, dated June 12,1 894.

Application filed March 12, 1894.

To aZZ whom it may concern:

Be it known that I, CHARLES M. CARNAHAN, a citizen of the United States,residing at Newport, Campbell county, State of Kentucky, have inventedcertain new and useful Improvements in Envelopes, of which the follow--ing is a specification, reference being bad to the accompanyingdrawings.

My invention relates more especially to envelopes for. use in mailing'or shipping merchandise, catalogues, &c., in unsealed packages. v

The nature of my invention will be apparent from the detaileddescription and claim hereinafter contained. I

In the accompanying drawings:--Figure 1, is a perspective view of myimproved envelope in a closed position, and Fig. 2, is a simi lar viewwith the end flaps opened. Fig. 3 is a central longitudinal sectiontaken through the envelope and fastener shown in Fig. 2.

The body of the envelope consists of an integral piece of suitablematerial cut, creased and folded in the usual manner with end flapsa,b,-the main body portion having its edges overlapped forming a doublethickness of material as shown in Fig. 3 and by dotted lines in Fig. 2.The fiap b is preferably glued and then pasted to the main body of theenvelope, as shown.

My invention relates more especially to the means shown for fasteningthe end flap a of an envelope such as hereinbefore described, said meansconsisting of a thin strip of suitable metal D having its end portionsbent upward forming tangsd, d which latter are passed from withinoutward through the doubled portion of the main body of the envelope, asshown in Figs. 2 and 3. The tangs d and d are so located in the mainbody of the envelope, with reference to its'flap a, so that when thelatter is folded or pressed down the Serial No. 503,245. (No model-Jtang (Z will pass through said -flap,the front edge or end of the latterreaching almost or quite up to the vertical tang d. The tangs d thefastening of the flap a, as shown in Fig. 1.

The advanta es of m invention consist in its simplicity of constructionand operation,

cheapness of manufacture and security afforded for fastening the endflap. It will be observed that the point or apex of the flap a iscovered and securely locked in place by the tang cl, which latteraffords a protection to said flap where most needed. This constructionprotects the point of the flap from coming into contact with otherobjects, which contact would otherwise have a tendency to throw saidflap upward and open the package. An envelope provided with myimprovedfastener is quite readily opened for inspection of its contents, when sodesired by simply bending the taugs upward.

I am aware that it is not new, broadly, to fasten the flap of anenvelope with a staple having two tangs adapted to be bent outward fromeach other, (such as the McGill fastener) and I lay no claim to such adevice; but,

What I claim as new, and desire to secure by Letters Patent, is-

An envelope having theeud flap a, in combination with the metallic stripD having tangs d and (1 passed outward through the body portion of theenvelope, one of said tangs being passed through said flap andcompressed downward thereon toward its point, the other tang beingcompressed and bent upward overlapping the point of said flap whenclosed, as set forth.
